Basic algebra, functions, descriptive statistics, and introductory linear algebra are enough to begin a beginner course; calculus becomes more useful when you want to understand how models learn, while theory-focused courses may expect much more. The right amount depends on whether you want to use models, build them, understand their training, or study their mathematical foundations.
What math should you know to get started?
For a practical first course, focus on being comfortable with variables, linear equations, graphs of functions, histograms, and statistical means. Google’s Machine Learning Crash Course prerequisites also mention logarithms and the sigmoid function, and list matrix multiplication and tensor concepts as useful background. These are course-specific recommendations, not a demand to finish a university math sequence before beginning.
A useful starting checklist is:
- Rearrange basic equations and work with variables.
- Read a function graph and understand how changing an input affects an output.
- Interpret an average and a histogram; build toward understanding variation and distributions.
- Recognize vectors and matrices, and follow what matrix multiplication does.
If one item is unfamiliar, you can study it as it arises in your ML lessons rather than treating it as a reason to postpone them.
Which math matters most as you progress?
Linear algebra: the most recurring foundation
Start with vectors, matrices, and matrix multiplication. These give you a way to understand how data and model parameters are represented and combined. As you move into more advanced material, useful topics include subspaces, bases, orthogonality, singular value decomposition, and eigendecomposition. Columbia’s 2026 Math for Machine Learning course includes these deeper topics, illustrating how far a math-focused treatment can go beyond introductory matrix concepts.
#1 Best Overall
Probability and statistics: reasoning about data and uncertainty
Begin with averages, variation, and distributions. Probability and statistics become increasingly important when you evaluate model behavior, reason about uncertainty, or study how learning methods work. Stanford’s CS129 Machine Learning course lists basic probability among its prerequisites. Columbia’s 2026 course assumes undergraduate probability and statistics and covers topics such as estimators, bias and variance, distributions, and maximum likelihood.
Calculus: useful for understanding training, not a universal starting gate
Google lists calculus as optional for advanced topics in its Crash Course and points learners to derivatives, gradients, partial derivatives, and the chain rule for understanding backpropagation. These ideas explain how a model’s parameters are adjusted to reduce error. You can begin practical study without them, but learning them makes the mechanics of optimization and neural-network training easier to follow.

For a direct explanation of how matrix calculus connects to deep learning, Terence Parr and Jeremy Howard’s 2018 paper, “The Matrix Calculus You Need For Deep Learning,” is aimed at readers who already know neural-network basics and want to deepen their understanding of the underlying math. It is a follow-on resource, not a prerequisite for learning to train or use deep-learning models.
How much math do different learning goals require?
There is no single math requirement attached to “AI.” The expected preparation varies with the course’s scope and rigor. These examples describe particular courses, not universal requirements for every learner or job.
| Learning goal or course | Math expectation | What that means for you |
|---|---|---|
| Begin a practical introductory course | Google’s Machine Learning Crash Course recommends algebra, function graphs, histograms, and statistical means; matrix multiplication and tensor concepts are useful background. Calculus is optional for advanced topics. | Start with the basics and fill gaps as you encounter them. |
| Take an applied university ML course | Stanford CS129 lists basic probability and linear algebra, as well as programming. | Review probability and linear algebra before or alongside the course. |
| Study mathematical foundations of ML | Columbia’s Summer 2026A Math for Machine Learning course assumes undergraduate linear algebra, multivariable calculus, and probability/statistics. | Expect a substantial foundation before the course; these assumptions are not barriers to beginning practical AI study. |
| Study rigorous graduate-level theory | MIT OpenCourseWare’s Mathematics of Machine Learning syllabus for Fall 2015 lists real analysis, linear algebra, and probability/statistics. | This graduate-level example shows that theoretical study can require considerably more math. Its syllabus is from 2015 and should be read in that context. |
A practical order for learning the math
For many beginners, it is more useful to pair math with an introductory ML course than to try to master every topic in isolation. This is a practical sequencing choice, not a prerequisite rule shared by all courses.
- Begin with algebra and data basics. Review variables, linear equations, function graphs, averages, and histograms while starting an introductory course.
- Add basic linear algebra. Learn vectors, matrices, and matrix multiplication as models and lessons begin using them.
- Strengthen probability and statistics. Add distributions, variation, and probability as you move from following examples to evaluating results and model behavior.
- Study calculus when you want to understand training. Focus on derivatives, gradients, partial derivatives, and the chain rule to make optimization and backpropagation more intelligible.
- Go deeper according to your goal. For mathematical foundations, prepare for multivariable calculus, more advanced linear algebra, and probability/statistics; rigorous theory may call for real analysis.
If you prefer a structured foundation, Columbia’s course page recommends Mathematics for Machine Learning by Deisenroth, Faisal, and Ong as a reference. It is an optional resource, not a condition for getting started.
